Specification of Letters Patent.

Patent-ed Nov. 15, 15 221.

Application filed September 25, 1918. Serial No. 255,559.

To all whom it may concern:

Be it known that I, JOHN P. EonnNRorH, a citizen of the United States,residing at Chester, in the county of Delaware, State of Pennsylvania,have invented new and useful Rolling-Mill for Bending Angle or ChannelIron into Difierent Angles, of which the following is a specification.

My invention relates to a rolling mill which is adapted to convert achannel iron of right angular form into one of different angles.

In the Letters Patent No. 1,267,194, granted to me on the 21st day ofMay, 1918, there is shown a rolling mill which is intended to convert achannel iron of right angular form into one of different angles, but thesame requires two distinct operations to change the opposite limbs ofthe channel iron, this being accomplished by converting one limb intothe desired angle, and then reversing the channel iron and repassing itthrough the mill whereby the other limb is converted into the desiredangle.

The present invention consists in the employment of means whereby both.limbs of a channel iron may be converted from their right angular forminto angles of other degrees, this being accomplished by one pass of thesaid iron through the mill, thus saving time and labor, and furtherreducing the expense of operation by the employment of one heat.

The invention is satisfactorily illustrated in the accompanying drawing,but the important instrumentalities thereof may be varied, and so it isto be understood that the invention is not limited to the specificdetails shown and described, long as they are within the spirit or scopeof the claims.

Figure 1 represents a top or plan view of a rolling mill embodying myinvention.

Fig. 2 represents a transverse vertical section on line 2-2 Fig. 1.

Fig. 3 represents a transverse vertical sec tion on line 3-3 Fig. 1.Fig. 4 represents a longitudinal section of a portion thereof on line 4Fig. 1.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings 1 and 2 designate guide rolls mounted on theopposite ends of the frame of the mill, and 3 designates alongitudinallyextending bed plate on said frame adapted to support achannel iron in its pass through the mill. in the upper part of thevertical housing 4 on the frame of the mill is swiveled the screw orscrew shaft 5 on which is fitted the traveler nut 6 which is formed withgudgeons extending laterally therefrom and having hearings in the ears 8of a rocker or rocker block 9, the latter being provided with segments10 which have hearings on the adjacent portions of the housings.

In said rocker block 9 are mounted the upper journals oruaxes 11 and 12respectively of rolls 13 and 14: which arev placed inclined or obliqueside by side in vertical direction. a

The lower end of the roll 13 has a gudgeon 15 which has a bearing in therocker or pillow blocks 16 which are mounted on the adjacent portions ofthe housing 4. The memaers thus far described are similar to those shownin the patent referred to, it being evident that in the pass of thechannel iron through the mill, one limb of said iron is passed betweenthe rolls 13 and 1e and so bent from a right angle to an acute angle orinclination, as shown in Fig. 2. If the angularity of the other limb orflange is to be changed the iron requires to be reversed after which itis again passed through the said rolls 13 and 14 as explained in saidpatent.

On the frame of the mill is the vertical housing 17 which is forward ofthe housing 4 In the upper part of said housing 17 is swiveled the screwor screw shaft 18 on which is fitted the traveler nut 19 which is formedwith gudgeons 20 extending laterally therefrom and having bearings inthe ears 21 of arocker or rocker block 22, the latter being providedwith segments which have bearings on the adjacent portions of thehousing 17.

In said rocker block 22 are mounted the upper journals or axes 23 and 24of rolls 26 and 25 respectively which are placed inclined or obliquelyside by side in vertical direction and are diagonal to the rolls 13 and14. The lower end of said roll has thereon the gudgeons 27 which havehearings in the rocker or pillow block 28 which is mounted on theadjacent portion of the housing 17, the lower end of the rolls 14; and26 being similarly mounted, as seen in Figs. 2 and 3,

' subjected it being seen that the inclination of the rolls and 26 is ina direction the reverse of the rolls 13 and 14, it being noticed thateither air of rolls is adapted to be adjusted in inclination independentof the other, this being accomplished by the operation of the respectivescrews or screw shafts 5 and 18.

Now after the channel iron is passed through the mill between the rollsl3 and '14 and has one of its limbs bent from a right angle to an acuteangle, leaving the other limb right angular, both as shown in Fig. 2 ashas been stated, the said iron continues itspassage and reaches therolls 25 and 26 when the remaining right angular limb enters betweensaid rolls 25 and 26 and is bent thereby into an acute angle as shown inFig. 3, so the said iron passes through the mill to the oppositelimb-bending ac tions of the two pairs of rolls, this being accomplishedin one pass, the advantages of which has been hereinbefore stated.

It isevident also that as each pair of rolls has its individualadjustment as to inclination the opposite limbs of the channel iron maybe bent in angles variable or different from each other according torequirements.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is i 1. In a rolling mill of the characterstated, a pair of bending rolls of difierent lengths, a second pair ofbending rolls of different lengths, a rocker bearing for the gudgeons atone end of each of said pairs of rolls, and an independent rockerbearing for the other end of each of the longer rolls, said rolls beingarranged toac't upon and bend both limbs of a channel iron during asingle pass thereof through said rolls.

2. In a rolling mill of the character stated, a pair of bending rolls ofdifferent lengths, a second pair of bending rolls of different lengths,a rocker bearing for the gudgeons at one end of each of said pairs ofrolls, and an independent rocke bearing for the other end of each of thelonger rolls, said rolls being arranged to act upon and bend both limbsof a channel iron during a single pass thereof through said rolls, andmeans for ad justing the inclination of each of said pairs of rolls.
